PurposeThe catastrophic effects of the COVID-19 pandemic have considerably impacted the labour market and increased job insecurity among workers. This study systematically reviews the literature on job insecurity conducted in the context of the COVID-19 pandemic with three key objectives. First, to identify the key antecedents of job insecurity during the pandemic. Second, to identify the outcomes associated with job insecurity during the pandemic. Third, to identify the underlying boundary conditions that strengthened or alleviated the association between the antecedents of job insecurity and its associated outcomes.Design/methodology/approachThe study followed PRISMA 2020 guidelines for the selection and inclusion of scientific literature by systematically searching five electronic databases, namely, Scopus, ScienceDirect, PubMed, Web of Science and Psych Info.FindingsA perception of health-related risks, negative economic consequences and organizational restructuring during the pandemic were the primary factors contributing to job insecurity among workers. The consequences encompassed detrimental impacts on health and well-being, proactive measures undertaken by employees to alleviate the threat of job loss, and a variety of tactics employed to cope with stress arising from job insecurity. The boundary conditions elucidate the factors that alleviated job insecurity among workers and influenced both their work and non-work outcomes.Originality/valueThis is the first systematic review summarizing the literature on employees' experiences with job insecurity amid the COVID-19 pandemic. Based on a systematic review, this study provides doable steps that HR managers can take to effectively manage job insecurity among workers, particularly during a crisis.
